PPlus is a simple environment to execute Python code in parallel on many
machines without much effort.
It is actually a fork of Parallel Python,
another simple but powerful framework for parallel execution of python code,
which lacks features needed for effective use in our daily research.

More specifically, PPlus was created to answer following needs:

to facilitate data transport over distributed environment of usually
very big file, exposing a simple interface while handling details
in the background

to separate file handling between different experiments, so one machine can
participate in many computational experiments simultaneously
